Mid-End ASIC Engineer, Senior

Positron AI, Austin, TX 78701 Hybrid work

Job Description

Positron AI is a leader in developing custom hardware systems designed to enhance AI inference performance and efficiency. We are seeking a Senior Mid-End ASIC Engineer to take charge of synthesis, timing convergence, and logical design quality for our AI accelerator roadmap. This role requires a hands-on approach to transform high-quality RTL into implementation-ready netlists while ensuring effective collaboration across various engineering teams.

Responsibilities

Define and own synthesis methodology for current and future ASIC generations. Conduct hands-on synthesis using EDA tools like Cadence Genus and Synopsys Design Compiler. Develop and maintain SDC constraints and timing budgets. Drive logical timing closure and optimization across multiple parameters. Perform root-cause analysis of timing bottlenecks. Collaborate with architecture and RTL teams to mitigate timing risks. Partner with backend engineers for physical-aware optimization and timing budgeting. Lead cross-functional execution with various engineering teams to resolve issues rapidly. Serve as the synthesis technical lead with external partners, reviewing QoR and timing reports. Apply AI techniques to enhance timing analysis and engineering automation.

Qualifications

12+ years of ASIC implementation experience with successful tapeouts. Expertise in synthesis methodology and flow development. Deep knowledge of timing closure for complex designs. Proficiency in Cadence Genus and/or Synopsys Design Compiler. Strong SDC expertise and constraint development skills. Understanding of RTL design principles and implementation-friendly practices. Hands-on experience with advanced process nodes (5nm and below). Strong Tcl and Python scripting skills for automation. Excellent debugging and root-cause analysis capabilities.
